X-Men is a home console video game produced by Sega in 1993, based on the adventures of the Marvel Comics superhero team, the X-Men. One or two players can play as any of four pre-chosen X-Men. X-Men is a Mega Drive/Genesis-exclusive game and in 1995 was followed up by X-Men 2: Clone Wars.
The game takes place in the Danger Room, a training area for the X-Men inside the X-Mansion. A virus transmitted via satellite has infected the Danger Room, disabling control and safety limits. The X-Men must endure the unpredictable behavior of the Danger Room until the virus can be located and eliminated. Once the virus is eliminated, the X-Men discover that Magneto is behind the computer virus and the final stage involves a battle with him.
Gambit, Nightcrawler, Wolverine, and Cyclops are available to play. Each character can jump and use various unlimited weapons (i.e. punch, kick) and a superpower which had a usefulness limited by a mutant power bar similar to a life meter, making the player rely more on standard attacks. The mutant power bar would slowly regenerate when depleted and when switching characters in mid-game, would revert to the status of the next characters mutant power bar from the last use (characters yet to be used would start off with a standard full bar of mutant power).
